Estimate the unit rate if 12 pairs of socks sell for $5.79.

The unit rate for one pair of socks is 0.4825$

This is because we have the price for a dozen which is 5.79, so to calculate one pair we can simply divide the price of the dozen by the number in a dozen which is obviously 12.

So 5.79 dollars divided by 12 comes out be 0.4825$. We can further round off 0.4825 correct to 3 significant figures and write it as 0.483 which looks a little more user friendly number,

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
